1 Peter 2:18-20

You who are slaves must submit to your masters with all respect. Do what they tell you—not only if they are kind and reasonable, but even if they are cruel. For God is pleased when, conscious of his will, you patiently endure unjust treatment. Of course, you get no credit for being patient if you are beaten for doing wrong. But if you suffer for doing good and endure it patiently, God is pleased with you.
